The blood components obtained from apheresis offer greater safety to patients at the time of blood transfusion; verifying leukoreduction differentiator Material and Methods: A descriptive study was perfor-med cross-sectional in Colombia Hematológica Foundation. Bogotá. Simple random sampling was performed from the list entered in a blood drive for the purpose of ve-rification of residual white blood cell count by Nageotte chamber and Cell Dyn Ruby © © units.

Results: The study population consisted of 124 samples of platelets obtained by apheresis. In relation to cell count for the two methodologies presented an average of 0,057 vs 0,003 cells counted; the maximum value for the two methods was 0.34 to 0.44. Conclusions: The samples analyzed presented residual white blood cell counts below 5.0 x 106 estimated to set the drive as leukoreduced with this finding value puts safety of transfused platelets obtained by apheresis aspects reactions to evidence transfusion rWBC additionally could be used safely leaving platelets into consideration the use of filters to leucorredución.
